By exercising the Licensed Rights (defined below), You accept and

Commons Attribution-ShareAlike 4.0 International Public License
("Public License"). To the extent this Public License may be

Section 1 – Definitions.

   Adapted Material means material subject to Copyright and Similar
   Rights that is derived from or based upon the Licensed Material
   and in which the Licensed Material is translated, altered,
   arranged, transformed, or otherwise modified in a manner requiring
   permission under the Copyright and Similar Rights held by the
   Licensor. For purposes of this Public License, where the Licensed
   Material is a musical work, performance, or sound recording,
   Adapted Material is always produced where the Licensed Material is
   synched in timed relation with a moving image.

   Adapter's License means the license You apply to Your Copyright
   and Similar Rights in Your contributions to Adapted Material in
   accordance with the terms and conditions of this Public License.
   BY-SA Compatible License means a license listed at
   creativecommons.org/compatiblelicenses, approved by Creative
   Commons as essentially the equivalent of this Public License.

   Copyright and Similar Rights means copyright and/or similar rights
   closely related to copyright including, without limitation,
   performance, broadcast, sound recording, and Sui Generis Database
   Rights, without regard to how the rights are labeled or
   categorized. For purposes of this Public License, the rights
   specified in Section 2(b)(1)-(2) are not Copyright and Similar
   Rights.

   Effective Technological Measures means those measures that, in the
   absence of proper authority, may not be circumvented under laws
   fulfilling obligations under Article 11 of the WIPO Copyright
   Treaty adopted on December 20, 1996, and/or similar international
   agreements.

   Exceptions and Limitations means fair use, fair dealing, and/or
   any other exception or limitation to Copyright and Similar Rights
   that applies to Your use of the Licensed Material.

   License Elements means the license attributes listed in the name
   of a Creative Commons Public License. The License Elements of this
   Public License are Attribution and ShareAlike.

   Licensed Material means the artistic or literary work, database,
   or other material to which the Licensor applied this Public
   License.

   Licensed Rights means the rights granted to You subject to the
   terms and conditions of this Public License, which are limited to
   all Copyright and Similar Rights that apply to Your use of the
   Licensed Material and that the Licensor has authority to license.

   Licensor means the individual(s) or entity(ies) granting rights
   under this Public License.

   Share means to provide material to the public by any means or
   process that requires permission under the Licensed Rights, such
   as reproduction, public display, public performance, distribution,
   dissemination, communication, or importation, and to make material
   available to the public including in ways that members of the
   public may access the material from a place and at a time
   individually chosen by them.

   Sui Generis Database Rights means rights other than copyright
   resulting from Directive 96/9/EC of the European Parliament and of
   the Council of 11 March 1996 on the legal protection of databases,
   as amended and/or succeeded, as well as other essentially
   equivalent rights anywhere in the world.

   You means the individual or entity exercising the Licensed Rights
   under this Public License. Your has a corresponding meaning.

Section 2 – Scope.

   License grant.
       Subject to the terms and conditions of this Public License,
       the Licensor hereby grants You a worldwide, royalty-free,
       non-sublicensable, non-exclusive, irrevocable license to
       exercise the Licensed Rights in the Licensed Material to:

           reproduce and Share the Licensed Material, in whole or in part;
           and produce, reproduce, and Share Adapted Material.

       Exceptions and Limitations. For the avoidance of doubt, where
       Exceptions and Limitations apply to Your use, this Public
       License does not apply, and You do not need to comply with its
       terms and conditions.

       Term. The term of this Public License is specified in Section
       6(a).

       Media and formats; technical modifications allowed. The
       Licensor authorizes You to exercise the Licensed Rights in all
       media and formats whether now known or hereafter created, and
       to make technical modifications necessary to do so. The
       Licensor waives and/or agrees not to assert any right or
       authority to forbid You from making technical modifications
       necessary to exercise the Licensed Rights, including technical
       modifications necessary to circumvent Effective Technological
       Measures. For purposes of this Public License, simply making
       modifications authorized by this Section 2(a)(4) never
       produces Adapted Material.

       Downstream recipients.

           Offer from the Licensor – Licensed Material. Every
           recipient of the Licensed Material automatically receives
           an offer from the Licensor to exercise the Licensed Rights
           under the terms and conditions of this Public License.

           Additional offer from the Licensor – Adapted
           Material. Every recipient of Adapted Material from You
           automatically receives an offer from the Licensor to
           exercise the Licensed Rights in the Adapted Material under
           the conditions of the Adapter’s License You apply.

           No downstream restrictions. You may not offer or impose
           any additional or different terms or conditions on, or
           apply any Effective Technological Measures to, the
           Licensed Material if doing so restricts exercise of the
           Licensed Rights by any recipient of the Licensed Material.

       No endorsement. Nothing in this Public License constitutes or
       may be construed as permission to assert or imply that You
       are, or that Your use of the Licensed Material is, connected
       with, or sponsored, endorsed, or granted official status by,
       the Licensor or others designated to receive attribution as
       provided in Section 3(a)(1)(A)(i).

   Other rights.

       Moral rights, such as the right of integrity, are not licensed
       under this Public License, nor are publicity, privacy, and/or
       other similar personality rights; however, to the extent
       possible, the Licensor waives and/or agrees not to assert any
       such rights held by the Licensor to the limited extent
       necessary to allow You to exercise the Licensed Rights, but
       not otherwise.

       Patent and trademark rights are not licensed under this Public
       License.

       To the extent possible, the Licensor waives any right to
       collect royalties from You for the exercise of the Licensed
       Rights, whether directly or through a collecting society under
       any voluntary or waivable statutory or compulsory licensing
       scheme. In all other cases the Licensor expressly reserves any
       right to collect such royalties.

Section 3 – License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

   Attribution.

       If You Share the Licensed Material (including in modified
       form), You must:

           retain the following if it is supplied by the Licensor
           with the Licensed Material:

               identification of the creator(s) of the Licensed
               Material and any others designated to receive
               attribution, in any reasonable manner requested by the
               Licensor (including by pseudonym if designated);

               a copyright notice;

               a notice that refers to this Public License;

               a notice that refers to the disclaimer of warranties;

               a URI or hyperlink to the Licensed Material to the
               extent reasonably practicable;

           indicate if You modified the Licensed Material and retain
           an indication of any previous modifications; and

           indicate the Licensed Material is licensed under this
           Public License, and include the text of, or the URI or
           hyperlink to, this Public License.

       You may satisfy the conditions in Section 3(a)(1) in any
       reasonable manner based on the medium, means, and context in
       which You Share the Licensed Material. For example, it may be
       reasonable to satisfy the conditions by providing a URI or
       hyperlink to a resource that includes the required
       information.

       If requested by the Licensor, You must remove any of the
       information required by Section 3(a)(1)(A) to the extent
       reasonably practicable.

   ShareAlike.

   In addition to the conditions in Section 3(a), if You Share
   Adapted Material You produce, the following conditions also apply.

       The Adapter’s License You apply must be a Creative Commons
       license with the same License Elements, this version or later,
       or a BY-SA Compatible License.

       You must include the text of, or the URI or hyperlink to, the
       Adapter's License You apply. You may satisfy this condition in
       any reasonable manner based on the medium, means, and context
       in which You Share Adapted Material.

       You may not offer or impose any additional or different terms
       or conditions on, or apply any Effective Technological
       Measures to, Adapted Material that restrict exercise of the
       rights granted under the Adapter's License You apply.

Section 4 – Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

   for the avoidance of doubt, Section 2(a)(1) grants You the right
   to extract, reuse, reproduce, and Share all or a substantial
   portion of the contents of the database;

   if You include all or a substantial portion of the database
   contents in a database in which You have Sui Generis Database
   Rights, then the database in which You have Sui Generis Database
   Rights (but not its individual contents) is Adapted Material,
   including for purposes of Section 3(b); and

   You must comply with the conditions in Section 3(a) if You Share
   all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.

Section 5 – Disclaimer of Warranties and Limitation of Liability.

   Unless otherwise separately undertaken by the Licensor, to the
   extent possible, the Licensor offers the Licensed Material as-is
   and as-available, and makes no representations or warranties of
   any kind concerning the Licensed Material, whether express,
   implied, statutory, or other. This includes, without limitation,
   warranties of title, merchantability, fitness for a particular
   purpose, non-infringement, absence of latent or other defects,
   accuracy, or the presence or absence of errors, whether or not
   known or discoverable. Where disclaimers of warranties are not
   allowed in full or in part, this disclaimer may not apply to You.

   To the extent possible, in no event will the Licensor be liable to
   You on any legal theory (including, without limitation,
   negligence) or otherwise for any direct, special, indirect,
   incidental, consequential, punitive, exemplary, or other losses,
   costs, expenses, or damages arising out of this Public License or
   use of the Licensed Material, even if the Licensor has been
   advised of the possibility of such losses, costs, expenses, or
   damages. Where a limitation of liability is not allowed in full or
   in part, this limitation may not apply to You.

   The disclaimer of warranties and limitation of liability provided
   above shall be interpreted in a manner that, to the extent
   possible, most closely approximates an absolute disclaimer and
   waiver of all liability.

Section 6 – Term and Termination.

   This Public License applies for the term of the Copyright and
   Similar Rights licensed here. However, if You fail to comply with
   this Public License, then Your rights under this Public License
   terminate automatically.

   Where Your right to use the Licensed Material has terminated under
   Section 6(a), it reinstates:

       automatically as of the date the violation is cured, provided
       it is cured within 30 days of Your discovery of the violation;
       or

       upon express reinstatement by the Licensor.

   For the avoidance of doubt, this Section 6(b) does not affect any
   right the Licensor may have to seek remedies for Your violations
   of this Public License.

   For the avoidance of doubt, the Licensor may also offer the
   Licensed Material under separate terms or conditions or stop
   distributing the Licensed Material at any time; however, doing so
   will not terminate this Public License.

   Sections 1, 5, 6, 7, and 8 survive termination of this Public
   License.

Section 7 – Other Terms and Conditions.

   The Licensor shall not be bound by any additional or different
   terms or conditions communicated by You unless expressly agreed.

   Any arrangements, understandings, or agreements regarding the
   Licensed Material not stated herein are separate from and
   independent of the terms and conditions of this Public License.

Section 8 – Interpretation.

   For the avoidance of doubt, this Public License does not, and
   shall not be interpreted to, reduce, limit, restrict, or impose
   conditions on any use of the Licensed Material that could lawfully
   be made without permission under this Public License.

   To the extent possible, if any provision of this Public License is
   deemed unenforceable, it shall be automatically reformed to the
   minimum extent necessary to make it enforceable. If the provision
   cannot be reformed, it shall be severed from this Public License
   without affecting the enforceability of the remaining terms and
   conditions.

   No term or condition of this Public License will be waived and no
   failure to comply consented to unless expressly agreed to by the
   Licensor.

   Nothing in this Public License constitutes or may be interpreted
   as a limitation upon, or waiver of, any privileges and immunities
   that apply to the Licensor or You, including from the legal
   processes of any jurisdiction or authority.
